Description

Technical Field

[0001] This application relates to the field of rock mechanics experiments, and in particular to a multi-module combined rock mechanics testing device. Background Technology

[0002] Currently, multifunctional, multi-module rock mechanics testing equipment is mainly used to test and study the mechanical and physical properties of rocks, such as strength, deformation, fracture, permeability, and seepage. Through experimental testing and data analysis, the mechanical and physical properties of rocks can be understood, providing important scientific basis and technical support for research and practice in fields such as geology, mining, and construction.

[0003] A multi-functional modular rock mechanics testing apparatus typically consists of the following main components: Testing equipment: including rock physical mechanics testing equipment, rock mechanical strength testing equipment, rock deformation and fracture testing equipment, etc., used to test different mechanical properties of rocks. Data acquisition and processing system: used to collect experimental data and perform data processing and analysis, such as data acquisition instruments and computers. Control system: used to control the testing equipment and data acquisition system, such as controllers and sensors.

[0004] Regarding the aforementioned technologies, when mechanical testing of rocks is required, there are many different rock sample sizes. Rocks that are too large or too small are not easy to clamp, requiring staff to select rocks of suitable size for testing, which increases the workload of the staff. Summary of the Invention

[0005] To reduce the workload of staff, this application provides a multi-module combined rock mechanics testing device.

[0006] This application provides a multi-module combined rock mechanics testing device, which adopts the following technical solution:

[0007] A multi-module combined rock mechanics testing device includes a base, an upper end of which is provided with a testing mechanism for detecting rock strength, a collection box for storing rocks, a grid plate for screening rocks inside the collection box, the grid plate being horizontally arranged, a pushing component for continuously pushing rocks on the upper surface of the grid plate, a filter plate for filtering rocks inside the collection box, the filter plate being arranged directly below the grid plate and parallel to the grid plate, and a conveying mechanism for transporting the screened rocks to the testing mechanism on one side of the collection box.

[0008] By adopting the above technical solution, when rocks need to be tested, the rocks are put into the collection box, the grid plate filters the rocks, and the pushing component moves the rocks, causing the rocks to constantly change position, which helps to reduce the phenomenon of rocks getting stuck. This makes it easier to filter out larger rocks, and the rocks fall onto the filter plate, which filters out smaller rocks, thus making it easier to select rocks of suitable size. This reduces the process of workers picking rocks and lowers the workload of workers. The conveying mechanism transports the screened rocks to the testing agency, where the testing agency tests the rocks and completes the rock mechanics test.

[0009] Optionally, the pushing assembly includes two rock-pushing plates, a connecting rod, and a pushing cylinder for pushing the connecting rod to move laterally. The pushing cylinder is horizontally positioned, and the two pushing plates are parallel to each other on the upper surface of the grid plate with a gap between them. The two ends of the connecting rod are respectively fixedly connected to one end of the two pushing plates. The piston rod of the pushing cylinder passes through the collection box and is connected to the outside of the connecting rod. The connecting rod is slidably connected to the collection box. When the piston rod of the pushing cylinder extends, the pushing plate moves linearly along the length of the grid plate.

[0010] By adopting the above technical solution, the workers transport the rock between the two push plates, start the push cylinder, push the piston rod of the cylinder to extend, drive the connecting rod to move laterally, and the connecting rod drives the two push plates to move laterally, thereby continuously pushing the rock, adjusting the position of the rock, and making it easier for the rock to pass through the grid plate, which helps to reduce the phenomenon of rocks getting stuck.

[0011] Optionally, the conveying mechanism includes a lever for pushing rocks off the filter plate into the collection box, a transverse cylinder for driving the lever to move laterally, a conveying hopper for conveying rocks, a support plate for carrying the conveyed rocks, a baffle for preventing rocks from rolling out of the support plate, a lifting cylinder for driving the baffle to rise and fall, and a transmission assembly for driving the support plate to move laterally to the detection mechanism. The transverse cylinder is connected to the collection box, and the piston rod of the transverse cylinder is connected to the lever. The collection box has a discharge port for rocks to pass through on the side away from the transverse cylinder. The conveying hopper is inclined at the discharge port of the collection box. The support plate is horizontally set on the upper surface of the base. The baffle is movably connected to the outside of the support plate. The lifting cylinder is vertically set inside the base, and the piston rod of the lifting cylinder is connected to the baffle.

[0012] By adopting the above technical solution, when the rock falls onto the filter plate, the transverse cylinder is activated. The piston rod of the transverse cylinder drives the deflector plate to move laterally. The deflector plate pushes the rock through the discharge port of the collection box, and the rock falls into the conveyor hopper. The conveyor hopper transports the rock, making the rock transport process more convenient. The conveyor hopper transports the rock to the support plate. The lifting cylinder drives the baffle plate to rise to one side of the support plate. The baffle plate blocks the rock, making it difficult for the rock to slip off the support plate. The transmission component drives the support plate to the detection mechanism to detect the rock.

[0013] Optionally, the transmission assembly includes two transverse lead screws, two connecting blocks for connecting the bearing plate, and a rotary motor for driving the transverse lead screws to rotate. The rotary motor is connected to the base, the two transverse lead screws are rotatably connected to the upper end face of the base and are parallel to each other, the two connecting blocks are threadedly engaged with the two transverse lead screws respectively, the lower end of the connecting block is slidably connected to the base, and the upper end of the connecting block is connected to the lower end face of the bearing plate.

[0014] By adopting the above technical solution, the rotating motor is started, and the output shaft of the rotating motor drives the transverse lead screw to rotate. The transverse lead screw drives the bearing plate to move laterally, thereby making the process of conveying rocks more convenient.

[0015] Optionally, the upper end of the base is provided with two support plates, and a support block is connected between the two support plates. The support block is located at the end of the support plate away from the base. The outer side of the support block is provided with a protective cover for covering the detection mechanism. The support block is provided with a linkage component for driving the protective cover to rise and fall.

[0016] By adopting the above technical solution, the support plate supports the support block, and the support block supports the protective cover. When the rock is transported, the linkage component is activated, which drives the protective cover to descend, covering the detection mechanism and the rock. This helps to reduce the phenomenon of rock fragments splashing out and injuring people during detection.

[0017] Optionally, the linkage assembly includes a lifting screw for driving the lifting of the protective cover, a rotating gear for driving the lifting screw to rotate, and a drive rack for driving the rotating gear to rotate. The lifting cylinder is vertically arranged. The lower end of the lifting screw is rotatably connected to the support plate, and the upper end of the lifting screw is rotatably connected to the support block. The inner side of the protective cover is threadedly engaged with the lifting screw. A limiting block for restricting the movement direction of the protective cover is vertically provided on the inner side of the protective cover. The limiting block is slidably connected to the support plate. Grooves for the transverse screw to pass through are provided on both sides of the protective cover. The rotating gear is coaxially connected to the lower end of the lifting screw. The drive rack is connected to one side of the bearing plate and meshes with the rotating gear.

[0018] By adopting the above technical solution, the lateral movement of the bearing plate drives the lateral movement of the drive rack, which in turn drives the rotating gear to rotate. The rotating gear then drives the lifting screw to rotate, and the lifting cylinder causes the protective cover to descend. Thus, during the rock conveying process, the protective cover descends, the rock is conveyed to the testing mechanism, and the protective cover covers the testing mechanism, thereby improving testing efficiency.

[0019] Optionally, the testing mechanism includes three support frames, three telescopic cylinders, and three extrusion plates. The support frames are connected to the upper surface of the base, with one support frame facing one side of the bearing plate. When the bearing plate moves laterally to directly below the support block, the bearing plate is located between two of the support frames. The telescopic cylinders are connected to the support frames and are horizontally positioned. The piston rod of the telescopic cylinder is connected to the extrusion plate.

[0020] By adopting the above technical solution, the support frame supports the telescopic cylinder. When the rock is transported to the position directly below the support block, the telescopic cylinder is activated. The telescopic cylinder drives the extrusion plate to extrude the rock, which facilitates mechanical testing of the rock.

[0021] Optionally, the lower end face of the support block is provided with a flamethrower for spraying fire onto the rock, and the upper end of the flamethrower is connected to a drive cylinder for driving the flamethrower to rise and fall. The drive cylinder is set inside the support block and is set vertically.

[0022] By adopting the above technical solution, when a burning test is required on a rock, the flame gun is activated to burn the rock, which facilitates the burning test. When the flame gun is far away from the rock, the cylinder is activated, which extends the piston rod of the cylinder and moves the flame gun closer to the rock, thus making the burning process of the rock more convenient.

[0023] In summary, this application includes at least one of the following beneficial technical effects of a multi-module combined rock mechanics testing device:

[0024] 1. By setting up a grating plate and a filter plate, when rocks need to be tested, the rocks are put into the collection box, the grating plate filters the rocks, and the pushing component moves the rocks, causing the rocks to constantly change position, which helps to reduce the phenomenon of rocks getting stuck. This makes it easier to filter out larger rocks, and the rocks fall onto the filter plate, where the filter plate filters out smaller rocks, thus making it easier to select rocks of suitable size. This reduces the process of workers picking rocks and lowers the workload of workers. The conveying mechanism transports the screened rocks to the testing agency, where the testing agency tests the rocks and completes the rock mechanics test. Attached Figure Description

[0031] The present application will be further described in detail below with reference to all the accompanying drawings.

[0032] This application discloses a multi-module combined rock mechanics testing device.

[0033] Reference Figure 1 and Figure 2 A multi-module combined rock mechanics testing device includes a support mechanism 1, a screening mechanism 2, a conveying mechanism 3, a protective mechanism 4, and a testing mechanism 5. The screening mechanism 2, conveying mechanism 3, protective mechanism 4, and testing mechanism 5 are all connected to the support mechanism 1. The testing mechanism 5 is located inside the protective mechanism 4, and the conveying mechanism 3 and screening mechanism 2 are located on one side of the protective mechanism 4. When testing is required, the screening mechanism 2 screens the rocks to select rocks of suitable size. The conveying mechanism 3 transports the rocks to the testing mechanism 5. The protective mechanism 4 covers the testing mechanism 5 and the rocks for protection. The testing mechanism 5 then conducts the test on the rocks.

[0034] Reference Figure 1 and Figure 2 The support mechanism 1 includes a base 11, two support plates 12, and a support block 13. The support plates 12 are fixedly connected to the upper surface of the base 11 and are vertically arranged on both sides of the base 11. The support blocks 13 are fixedly connected to the upper ends of the support plates 12, and the support plates 12 and support blocks 13 are connected to each other on both sides. The support blocks 13 are horizontally arranged and connected to the protection mechanism 4 and the detection mechanism 5. The base 11 is connected to the screening mechanism 2 and the conveying mechanism 3. The base 11 supports the support plates 12, and the support plates 12 support the support blocks 13.

[0035] Reference Figure 1 and Figure 3 The screening mechanism 2 includes a collection box 21, a grid plate 22, a pushing assembly 23, and a filter plate 24. The collection box 21 is fixedly connected to one side of the base 11. The outer side of the grid plate 22 is fixedly connected to the inner wall of the collection box 21. The grid plate 22 is horizontally arranged. The pushing assembly 23 includes two pushing plates 231, a connecting rod 232, and a pushing cylinder 233. The pushing cylinder 233 is fixedly connected to the outer side of the collection box 21. The pushing cylinder 233 is horizontally arranged, and the piston rod of the pushing cylinder 233 passes through the collection box 21. The connecting rod 232 is fixedly connected to the connecting rod 232, which is parallel to the pushing cylinder 233. Two pushing plates 231 are fixedly connected to both ends of the connecting rod 232, and the pushing plates 231 are perpendicular to the connecting rod 232. The pushing plates 231 are slidably connected to the upper end face of the grid plate 22 and extend along the length of the grid plate 22. The outer side of the filter plate 24 is fixedly connected to the inner wall of the collection box 21. The filter plate 24 is horizontally arranged and located below the grid plate 22.

[0036] Reference Figure 1 and Figure 3 When testing rocks, the rocks are placed on the upper surface of the grating plate 22, positioned between the two push plates 231. The push cylinder 233 is activated, extending its piston rod and causing the connecting rod 232 to move laterally. The connecting rod 232 then moves the two push plates 231 laterally, repeatedly pushing the rocks. This facilitates adjusting the rock's position and allows it to pass through the grating plate 22, reducing the likelihood of rocks getting stuck. The rocks fall through the grating plate 22 onto the filter plate 24, which filters out smaller rocks, leaving rocks of suitable size above the filter plate 24. This facilitates the selection of appropriately sized rocks, reducing the time and workload for workers.

[0037] Reference Figure 2 and Figure 3The conveying mechanism 3 includes a deflector plate 31, a transverse cylinder 32, a conveying hopper 33, a bearing plate 34, a baffle plate 35, an elastic layer 36, a lifting cylinder 37, and a transmission assembly 38. The deflector plate 31 is slidably connected to the upper end face of the filter plate 24, and the deflector plate 31 is relatively parallel to the push plate 231. The transverse cylinder 32 is fixedly connected to the collection box 21, and the transverse cylinder 32 is horizontally arranged and relatively parallel to the push cylinder 233. The piston rod of the transverse cylinder 32 passes through one end of the collection box 21 and is fixedly connected to the deflector plate 31. A discharge port is opened on the side of the collection box 21 away from the transverse cylinder 32. 33 is fixedly connected to the discharge port of the collection box 21. The end of the conveying bucket 33 away from the collection box 21 is fixedly connected to the upper end of the base 11. The conveying bucket 33 is inclined. The bearing plate 34 is horizontally set on the upper surface of the base 11. The lifting cylinder 37 is fixedly connected inside the base 11. The lifting cylinder 37 is vertically set. The piston rod of the lifting cylinder 37 is fixedly connected to the baffle 35. The baffle 35 is vertically set and is set on the side of the bearing plate 34 away from the conveying bucket 33. The elastic layer 36 is fixedly connected to the side of the baffle 35 close to the bearing plate 34. The elastic layer 36 is evenly distributed.

[0038] Reference Figure 2 and Figure 3 After screening out rocks of suitable size, the transverse cylinder 32 is activated. The piston rod of the transverse cylinder 32 extends, driving the lever 31 to move laterally. The lever 31 pushes the rocks of suitable size to the discharge port. The rocks are then conveyed along the conveying bucket 33 to the baffle 35. The baffle 35 acts as a barrier against the rocks, which helps to reduce the phenomenon of rocks sliding out of the bearing plate 34. The rocks come into contact with the elastic layer 36, which helps to reduce the phenomenon of collision damage between the baffle 35 and the rocks, thus facilitating the conveying of the rocks.

[0039] Reference Figure 2 and Figure 3 The transmission assembly 38 includes two rotary motors 381, two transverse lead screws 382, ​​and two connecting blocks (not shown in the figure). The rotary motors 381 are fixedly connected to the base 11. The output shaft of the rotary motors 381 is coaxially connected to the transverse lead screws 382. The two transverse lead screws 382 are arranged in parallel. The two connecting blocks are threadedly engaged with the two transverse lead screws 382 respectively. The connecting blocks are slidably connected to the upper end face of the base 11. The upper end of the connecting blocks is fixedly connected to the lower end face of the bearing plate 34.

[0040] Reference Figure 2 and Figure 3 When the rock falls onto the support plate 34, the piston rod of the lifting cylinder 37 retracts, driving the baffle 35 to transport the rock into the base 11. The rotating motor 381 is started, and the output shaft of the rotating motor 381 drives the transverse screw 382 to rotate. The transverse screw 382 drives the connecting block to move laterally, and the connecting block drives the support plate 34 to move laterally. The support plate 34 transports the rock to the detection mechanism 5, thus making the rock transport process more convenient.

[0041] Reference Figure 3 , Figure 4 and Figure 5 The protective mechanism 4 includes a protective cover 41, a limiting block 42, and a linkage component 43. The protective cover 41 is made of acrylic material and is slidably connected to the outside of the support block 13. The limiting block 42 is fixedly connected to the inside of the protective cover 41 and is vertically arranged. The limiting block 42 is slidably connected to the support block 13 and the support plate 12. The linkage component 43 includes a lifting screw 431, a rotating gear 432, and a drive rack 433. The drive rack 433 is fixedly connected to the bearing plate. On the side of 34 near the support plate 12, the rotating gear 432 is rotatably connected to the support plate 12, the rotating gear 432 meshes with the drive rack 433, the rotating gear 432 is coaxially connected to the lifting screw 431, the lower end of the lifting screw 431 is rotatably connected to the support plate 12, the upper end of the lifting screw 431 is rotatably connected to the support block 13, the lifting screw 431 is vertically set, the protective cover 41 is threadedly engaged with the lifting screw 431, and two grooves are provided on both sides of the protective cover 41.

[0042] Reference Figure 3 , Figure 4 and Figure 5 During the rock transport process, the bearing plate 34 drives the drive rack 433 to move laterally. The drive rack 433 drives the rotating gear 432 to rotate, which in turn drives the lifting screw 431 to rotate. The lifting screw 431 then lowers the protective cover 41. The limit block 42 limits the movement of the protective cover 41, preventing it from shifting during the lifting process. When the bearing plate 34 is directly below the support block 13, the protective cover 41 abuts against the base 11, covering the detection mechanism 5 and the rock. The lateral screw 382 is positioned within the groove of the protective cover 41, which helps reduce the risk of rock fragmentation and injury during detection. Simultaneously, the lowering of the protective cover 41 during rock transport improves detection efficiency.

[0043] Reference Figure 3 , Figure 4 and Figure 5 The testing mechanism 5 includes three support frames 51, three telescopic cylinders 52, three extrusion plates 53, a flame gun 54, and a drive cylinder 55. The support frames 51 are located below the support block 13. When the bearing plate 34 moves horizontally to directly below the support block 13, the bearing plate 34 is located between two support frames 51, and the other support frame 51 is directly opposite the collection box 21. The telescopic cylinder 52 is fixedly connected to the support frame 51 and is horizontally set. The piston rod of the telescopic cylinder 52 is fixedly connected to the extrusion plate 53. The drive cylinder 55 is fixedly connected to the lower end face of the support block 13 and is located at the center of the support block 13. The drive cylinder 55 is vertically set, and the piston rod of the drive cylinder 55 is connected to the flame gun 54.

[0044] Reference Figure 3 , Figure 4 and Figure 5 The support frame 51 supports the telescopic cylinder 52. After the rock is transported to the area directly below the support block 13, the telescopic cylinder 52 is activated, extending its piston rod and causing the extrusion plate 53 to move laterally. The extrusion plate 53 then extrudes the rock, facilitating mechanical testing. When a burning test is required, the flame gun 54 is activated, burning the rock. When the flame gun 54 is far from the rock, the drive cylinder 55 is activated, extending its piston rod and bringing the flame gun 54 closer to the rock, making the burning process more convenient.

[0045] The implementation principle of a multi-module combined rock mechanics testing device according to an embodiment of this application is as follows: When a rock needs to be tested, the rock is placed on the upper surface of the grid plate 22 and located between the two push plates 231. The push cylinder 233 is activated, and the piston rod of the push cylinder 233 is extended, which drives the connecting rod 232 to move laterally. The connecting rod 232 drives the two push plates 231 to move laterally. The two push plates 231 repeatedly push the rock, and the rock falls through the grid plate 22 to the top of the filter plate 24. The filter plate 24 filters out rocks of smaller size, and then rocks of suitable size are left above the filter plate 24.

[0046] After screening out rocks of suitable size, the transverse cylinder 32 is activated. The piston rod of the transverse cylinder 32 extends, driving the paddle plate 31 to move laterally. The paddle plate 31 pushes the rocks of suitable size to the discharge port, and the rocks are conveyed along the conveying bucket 33 to the baffle 35.

[0047] When the rock falls onto the support plate 34, the piston rod of the lifting cylinder 37 retracts, causing the baffle 35 to be transported into the base 11. The rotating motor 381 is started, and the output shaft of the rotating motor 381 drives the transverse screw 382 to rotate. The transverse screw 382 drives the connecting block to move laterally, and the connecting block drives the support plate 34 to move laterally. The support plate 34 transports the rock directly below the support block 13.

[0048] During the process of conveying rocks, the bearing plate 34 drives the drive rack 433 to move laterally. The drive rack 433 drives the rotating gear 432 to rotate, which in turn drives the lifting screw 431 to rotate. The lifting screw 431 causes the protective cover 41 to descend. When the bearing plate 34 is conveyed directly below the support block 13, the protective cover 41 abuts against the base 11, covering the rocks. The lateral screw 382 is positioned within the groove of the protective cover 41. After the rocks are conveyed directly below the support block 13, the telescopic cylinder 52 is activated. The piston rod of the telescopic cylinder 52 extends, causing the pressing plate 53 to move laterally, which then presses the rocks.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
